Activate Cisco ASA 5505

A license specifies the functionalities (options) that are enabled on a given ASA. It is represented by an activation key which is a 160-bit (5 32-bit words or 20 bytes) value. This value encodes the serial number (an 11 character string) and the enabled features. Below are the steps I followed to license Cisco ASA 5505
